CLAMP FOR TYPE-WRITERS.

Patented July 24, 1906.

A li ti fil d March 13, 1905. Serial No. 249,703.

To all whom it may concern:

Be it known that I, ANTHONY J. THRoM, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New ork, haveinvented a new and useful Improvement in Olamps for Type-Writers, ofwhich the following is a specification.

This invention relates to the clamps employed for securing a type-writerto a baseboard, shelf, or other support.

The devices in common use consist ofbolts and similar fastenings whichmust be tightened from the under side of the desk, slide, or othersupport on which the machine is mounted, rendering it inconvenient inmany cases to fasten the clamps to the support. Such clamps also requirethe use of a wrench or special tool, and theholes for the bolts must bebored to suit the different styles of machines.

It is the object of my invention to simple fastening means for thiswhich can be conveniently applied and tightened from the upper side ofthe desk or other support without the use of tools and which can beadjusted to clamp machines of various styles and sizes.

In the accompanying drawings, Figure 1 is a side elevation of atype-writer fastened to its support by the improved clamps, the supportbeing shown in section. Fig. 2 is a sectional top plan view of theparts. Fig. 3 is a agmentary transverse section in line 3 3,

provide purpose Similar letters of reference indicate correspondingparts throughout the several views.

indicates a shelf, base-board, or other support on which the type-writerrests. This support is rovided under opposite frame members of thetype-writer, referably its side bars B, with transverse s ots 0, havingenlar ements c at one end. In the construction shown the enlargementsare at the inner ends of the slots.

D D indicate the improved clamps, each consisting of an upper rod orbolt (Z, adapted side bar B or other ame member of the typewriter, alower rod or bolt d, passing through the companion slot 0 and providedat its lower end with a ead or washer 0Z which bears against the underside of the support A, and a turnbuckle connecting said rods. The heads(1 are small enough to pass through the enlargements 0 of the slots 0,but wider than the latter, asshown. In the preferred construction shownin the drawings the upper rod 03 is the screw-threaded member engagingthe turnbuckle, and the same is provided with a hook d which embracesthe base-frame of the type-writer, this hook having a covering f, ofrubber or similar soft material, to prevent its marring the machine.

In fastening the machine to its support the lower rods (1 of the clampsare passed with their heads d through the enlargements of the slots 0from the upper side of the support and shifted into the narrow bodyportions of the slots. The type-Writer is then placed upon the support,between the clam s, the hooks d are enga ed over the framears B, and theturnbuck .es E are finally tightened, firmly securing the machine to Theslots permit the clamps to be adjusted crosswise of the support toaccommodate typewriters of different widths. can. be formed in the shelfor other support in the clamps, thus avoiding the trouble and delay ofsubsequently boring bolt-holes in the shelf to receive the fastenings,as heretofore. As the clamps are engaged with the shelf from its upperside, they can be conveniently applied, and as their ti htening membersare located above the she f they are also convenient of access.Moreover, no wrench or other tool of any kind is required to apply andtighten the clamps.

y arranging the enlargements c at the inner ends of the slots 0, asshown, they are located on the inner side of the frame of thetype-writer, and as the clamps are on the clamps from shifting inwardlyallow their heads or washers d to come into register with saidenlargements and become disengaged from the base-board A in case theclamps should become loose. rangement of the enlargements view,rendering tion more sightly than if the enlargements were at the outerends of the slots.

I claim as my invention- The combination of a type-writingmachine, abase-board or sup ort for the machine provided with a pair of transverseslots having far enough to enlargements arranged on the inner sides ofslot but wider than the body thereof, sub- I0 the side bars of themachine-frame, and a stantially as set forth. pair of clamps arranged onthe outer sides of Witness my hand this 7th day of March, said sideblars 811% palssing through said1 Sifts, 1905.
